3 Description

The DS90UB662-Q1 is a versatile sensor hub

capable of connecting serialized sensor data received

from four independent video data streams through a

FPD-Link III interface. When paired with a

DS90UB633A-Q1 or DS90UB63x CSI-2 serializer, the

DS90UB662-Q1 receives data from 1-Megapixel

image sensors supporting 720p/800p/960p/1MP

resolution at 30-Hz or 60-Hz frame rates. Data is

received and aggregated into a MIPI CSI-2 compliant

output for interconnect to a downstream processor.

The DS90UB662-Q1 includes four FPD-Link III

deserializers, each enabling a connection through

cost-effective 50-Ω single-ended coaxial or 100-Ω

differential STP cables. The receive equalizers

automatically adapt to compensate for cable loss

characteristics, including degradation over time.

Each of the FPD-Link III interfaces also includes a

separate low latency bidirectional control channel that

continuously conveys I2C, GPIOs, and other control

information. General-purpose I/O signals such as

those required for camera synchronization and

diagnostics features also make use of this

bidirectional control channel.

The DS90UB662-Q1 is AEC-Q100 qualified for

automotive applications and is offered in a cost-

effective and space-saving 64-pin VQFN package.
